It was Keselowski’s 34th career victory in 224 NASCAR Xfinity Series races, second victory and eighth top-10 finish in 2015 and his second victory and 12th top-10 finish in 16 races at TMS. The victory also helped allow Roger Penske to clinch his third consecutive owner’s championship in the NASCAR XFINITY Series.

“First off, Austin Dillon was really good and he was one of the toughest guys to beat,” Keselowski said. “He ran a heck of a race. Harvick looked really good, Kyle Busch looked really good and Kyle Larson I thought was going to run away with the race until he had that flat. There was a lot of competition out there today and that makes this win very special for the whole Discount Tire Ford team.”

A late caution set up a 16-lap duel between the three drivers when Kyle Larson cut a left rear tire and spun out in Turn 1. Dillon started out front followed by Keselowski, Erik Jones and Harvick. Keselowski passed Dillon with 11 to go and then Harvick began battling Dillon for second.

Keselowski ended up rolling to a 1.137-second margin of victory over Harvick. Dillon finished third, Jones fourth and Ty Dillon was fifth. Rounding out the top 10 in the 40-car starting field was Daniel Suarez, Brian Scott, Chase Elliott, Regan Smith and Elliott Sadler.

“Those closing laps were a great battle,” Keselowski said. “I was able to get alongside the 33 car (Dillon) and we were side by side for only a few laps, but it felt like forever. I saw the 88 (Harvick) coming with a chance to win and I was just able to clear the 33 and get by him. There was certainly a lot of stiff competition. Kevin Harvick looked really good, Austin Dillon, Kyle Busch, Kyle Larson all were major factors in the battle for this win, but we were able to persevere and overcome.”

Chris Buescher, who is the NASCAR Xfinity Series points leader, finished 11th and now has a 24-point lead over defending series champion Chase Elliott with two races remaining on the season schedule.

“We were trying to get something that was consistent going with our AdvoCare Mustang,” Buescher said. “The guys did a good job though and worked really hard to put a good piece on the race track. It wasn’t a bad day but not the day we were hoping for. All in all we just couldn’t get that one thing that was going to really turn our day around. There at the end we got a little too tight and I was just trying to keep adjusting on it to get it closer and probably over stepped. The guys did a nice job on pit road and they were consistent today. As far as points are concerned, that is a good points day but for a home race we were hoping to come out a little better.”
